Application filed January 3, 1920. Serial No. 349,164.

I '0 all whom it may concern:

Be it known that I, CHARLES Oscan TRACY, a citizen of the United States,and

a resident of Norwich, inthe county of New London and State ofConnecticut, have i11- vented a new and Improved Look, of which thefollowing is a full, clear, and exact description. y

This invention relates to looks, and has for an object to provide animproved construction in which a sliding hasp is used to connect thedifferent parts of the lock mechanism, and has a retalning member forholding two doors or other devices together.

Another object in view is to provide a lock substantially of the padlocktype in which. a sliding hasp is utilized, the arrangement being suchthat the hasp slides radially inwardly and outwardly to a locked andunlocked position respectively. y

A further object of the invention is to providea lock in which the hasp.is supported against the action of a hammer or other implement by aplurality of supporting members independent of the locking catch. 1

Another object of the invention is to provide a lock in which a slidingkey is used,

and a pivotally mounted catch associated vith a sliding bolt, thearrangement being such that the bolt is locked when slidinglv movedintoa locked position and unlocked when the key is slidingly moved to agiven position. a

In the accompanying drawing:

Figure 1 is a top plan view of a lock disclosing an embodimentof theinvention, the same being shown applied.

Fig. 2 is a sectional view through Fig. 1 on line 2--2.

Fig. 3 is a sectional view through Fig. 2 on line 3-3.

Fig. 4 is a sectional view similar to the right end of Fig. 3, but withthe catch shown in an unlocked position.

Fig. 5 is a fragmentary sectional view through Fig. 4 on line 5 5.

Fig. 6 is a detail perspective view showing the key guide embodyingcertain features of the invention.

Referring to the accompanying drawing by numerals, 1 and 2 may indicatedoors which are to be locked together. or any other article or devicedesired. The lock connecting these doors is formed in two principalparts, namely the hasp section 3 and the lock section 4. The haspsection 3 provided with a casingb similar in outside appearance to thecasing 6 of the lock section 1, though interiorlyit is quite different.As shown in Figs. 2 and 3, section 3 is provided with a bottom 7 havinga slot 8 merging into an enlar ement or head 9 through Which the hea 10of the bolt 11 is passed when being ad usted to the position shown inFig. 2. fWhen the bolt 11 is extending at right angles to the bottom 7the head 10 thereof will not pass through the opening 9 nor the slot 8,but will clamp section 3 in osition. Preferably the clamping action 1ssuch that the sectlon may easily slidetogether with the hasp or bolt 12.It will be noted that the hasp or bolt 12 provided with an arc-shapedflange or enlargement 13 fitting against the casing 6 while the bolthead 14. extends through a suitable slot 15 in casing 6 so that theshoulder 16 willinterlock with thelhook 17 of the locking catch 18. Thehead 14; isalso provided with an arc-shaped recess 19 for accommodatingthe bolt-20, which bolt is formed with a. headill fitting into arecess22 in the top of the cas ing 6, while the body of the bolt extendsthrough casing 6 and also through. door 1 so as to receive the clampingnut 23 and rigldly clamp the cas1ng6 inplace. The

casing 6 is preferably provided with a bottom 24 which is removablyarranged in the casing .6, and is provided with a short eX- tension 25fitting intothe notch 15 below the head 14., whereby the bottom cannotbe rotated independent of the casing 6, nor can the casing 6 be rotatedindependent of the bottom. To prevent rotation of the casing 6 andbottom 24, a plurality of pressed out spurs 26 are provided, which areforced into.

the door 1, said spurs co-acting with bolt 20 to prevent any rotarymovement, or in fact any movement whatever of the casing and the bottom.The catch 18 is pivotally mounted on a shaft 27 so as to freely swingthereon, said catch being acted upon by spring 28 so as to always have atendency to move to the position shown in Fig. 3. The catch 18 isprovided with an arm 29 having a plurality of arc-shaped fingers 30,acting in the capacity of tumblers, said fingers be ing arranged indifferent planes as shown in Fig. 5, so as to pass through the variousopenings 31 in a key 32 and also through the various openings 33 in thekey guide or ward 34. It will be noted that the spring path of movementof the key, when the key is forced in it may freely pass the'tumblers soas to engage the catch near point without any hindrance from thetumblers.

If an improper key is inserted it will move in until it contactswith thecatch at point 35, but cannot move the catch as any pivotal movement ofthe catch in a direction for releasing the same will cause the fingersor tumblers 30to press against the key. This will prevent any swingingmovement of the catch if the key, is an improper one, but if it isprovided with the proper slots 31 said slots will come opposite theopenings 33 and permit the passage of the tumblers 30. In order tochange the combination, the ward 34 is arranged in a slot in the bottom24: and held therein by rivets or in any other desired manner. It isintended that this ward shouldbe positioned at different points in theslot according to the combination desired, though if preferred it couldbe always arranged at the same place and the slots or openings 33varied. It is, of course, understood that the position of the fingers ortumblers 30 would be: varied to agree with the position of the slots 33.1 What I claim is:

1. A look of the character described comprising a bolt formed with anotch, a lock 2. A lock comprising a sliding hasp formed with a bolthcad having a hood at one end and said hood having a substantiallyT-shaped slot in the bottom, means formed with a head extending throughsaid slot for clamping the hasp to a body so that the hasp may slide andalso rotate after being disengaged, a lock casing fitting over said bolthead, and means in the casing for interlocking with the bolt head.

3. A lock comprising a bolt formed with a notch for'receivinga catchhaving an arcshaped notch in the end, said bolt having an arc-shapedshoulder, a lock casing fitting against said arc-shaped shoulder, aclamping bolt extending through the casing and fitting loosely against anotch in the end of the bolt, a pivotally mounted catch for looking saidbolt and engaging the bolt in said notch, and means for guiding a keyinto the casing for disengaging the catch.

4:. A lock comprising a bolt, a casing into which the bolt projects, apivotally mounted catch adapted to hold the bolt in a locked position, award for guiding a key into said catch for actuating the same, said wardbeing formed with a plurality of substantially transverse slots. and aplurality of areshaped fingers connected with said catch movable throughsaid slots when said hey disengagcs said catch whereby the key must beof the correct shape to permit the passage of said fingers betore saidcatch can be disengaged.

5. A lock of the character described comprising a casing, a catcharranged in said casing for ei'igaging a belt, a ward connected with thebottom of: the casing and formed so as to be positioned at difit'erontpoints in said bottom for varying the combination, said ward beingformed with a plurality of notches, and a plurality of fingers comiectedwith said catch movable through said notches when the catch is operatedby said key.
